**Forecast consensus points to a daytime high of 21–22°C in Qingdao on October 5, 2026, with market-implied probabilities clustered tightly around those outcomes.** Official guidance from the China Meteorological Administration and international models such as GFS and ECMWF show northwest winds of 4–7 levels moderating coastal temperatures during the autumn transition. Clear to partly cloudy skies are expected to allow moderate solar heating, yet stronger afternoon winds and marine influence from the Yellow Sea limit the peak. Historical early-October normals near 20–22°C provide context, while minor model differences in wind timing and cloud cover explain the narrow spread among 21°C, 22°C, and 23°C bins. Traders are weighting the most recent short-range runs, which show little deviation from this range as the date approaches.
